Just because it increases recovery time, don't think people who use train more often. They usually don't.

Just to throw this into the mix:

Those with high levels of anabolic support in their body's won't necessarily have to train as often as those training without support. The anabolics will help to maintain an anabolic environment throughout the week. It's those who are training without anabolic support who require the *mechanical stimulus* (i.e. training with weights) every couple of days to maintain the stimulation from weights throughout the week.
